Despite its advantages, EPR also faces several challenges in the field of nanotechnology:
Sample preparation: Preparing nanomaterials for EPR analysis can be challenging, especially if the materials are sensitive to environmental conditions. Interpretation of spectra: The interpretation of EPR spectra can be complex, particularly for systems with multiple magnetic interactions or overlapping signals. Size effects: The small size of nanoparticles can lead to broadening and shifting of EPR signals, complicating the analysis.
